Dad attends son's graduation wearing tie he made in first grade

June 5 (UPI) -- A Texas dad warmed the hearts of Twitter by attending his son's graduation proudly wearing the Pokemon tie the boy made for him in first grade.

Dylan Olivo, 18, tweeted a photo from his high school graduation in Austin showing him posing with his father, who is wearing a tie featuring a hand-drawn Pikachu surrounded by Pokeballs.

"I made this tie for my dad when I was in 1st grade. 11 years later he wears it to my graduation," Olivo wrote.

"I still remember making the tie for him, and I think he does too," Olivo told Teen Vogue. "He had it planned this whole time to wear it."

He said he was "shocked" when his dad showed up to graduation wearing the tie.

"I didn't expect him to really wear it or even have it this whole time. He has never worn the tie before in his life until my graduation day," Olivo said.
